The mother of a Liverpool hostage who was murdered in an armed siege at an Algerian gas plant is breaking her silence to condemn the way British officials responded to the terrorist attack.

Garry Barlow was killed on his 50th birthday when militants stormed the desert plant where he was working as a systems engineer.

His family say they're still in the dark over exactly how he was killed and they're demanding the government put more pressure on the Algerian authorities to explain why their rescue operation went so wrong.

In her first television interview Garry's mother Margaret is now calling for a full inquiry.
